Public Broadcasting

Use a third-party public broadcaster to sign a private transaction and broadcast to the blockchain nodes. This provides more anonymity.

Note: Public broadcasters do not ever gain control or custody of your funds and cannot see any details of the sender or the contents of the private transaction. Railway does not control or maintain any broadcasters in the decentralized public broadcaster network.

When you select "public broadcaster" you will see a variety of public broadcast options.

Fee Ratio

At the top of each option is the Fee Ratio. When using a public broadcaster, you are buying gas using a fee token. The "Fee ratio" is the premium or discount you are paying for gas relative to the token you are using.

Railway Wallet performs a gas estimation which is then expressed as a ratio to your fee token.

For example, in the image below, according to the gas estimate, it would cost you 0.91 ETH to get 1 ETH worth of gas. It doesn't actually cost 1 ETH to send the transaction, it's just an indication of the premium to use a broadcaster.

The amount is lower because transactions rarely consume the whole gas estimate (usually about 80-90% of the gas estimate is consumed) and the broadcaster will take the difference as a reward for broadcasting the transaction.

The lower the number on the left, the less the transaction will cost you.

​

Rankings range from green, yellow, and red based on railway reliability. If you select Random Broadcaster it will automatically assign a broadcaster with higher reliability.

Below the broadcaster options we can change the fee token. Generally speaking, it is best to pay the fee token with the same token you are trying to transact with. Make sure to set your fee token to a wallet with adequate balance.

Review the transaction and click generate proof.

If a broadcast fails, click "retry broadcaster" and it will select the next best broadcaster option. Keep trying until the transaction succeeds.
